The Achilles tendon is the largest tendon in the body; connecting the calf muscles to the heel. An Achilles tendon rupture prevents the tendon from performing its function of pulling the foot and ankle downward during walking, running and jumping. Most ruptures occur about four to six inches above the heel, but the tendon can also tear where it meets the heel bone.
As with any muscle or tendon in the body, the Achilles tendon can be torn if there is a high force or stress on it. This can happen with activities which involve a forceful push off with the foot, for example, in football, running, basketball, diving, and tennis. The push off movement uses a strong contraction of the calf muscles which can stress the Achilles tendon too much. The Achilles tendon can also be damaged by injuries such as falls, if the foot is suddenly forced into an upward-pointing position, this movement stretches the tendon. Another possible injury is a deep cut at the back of the ankle, which might go into the tendon. Sometimes the Achilles tendon is weak, making it more prone to rupture. Factors that weaken the Achilles tendon are as follows. Corticosteroid medication (such as prednisolone) - mainly if it is used as long-term treatment rather than a short course. Corticosteroid injection near the Achilles tendon. Certain rare medical conditions, such as Cushing's syndrome, where the body makes too much of its own corticosteroid hormones. Increasing age. Tendonitis (inflammation) of the Achilles tendon. Other medical conditions which can make the tendon more prone to rupture; for example, rheumatoid arthritis, gout and systemic lupus erythematosus (SLE), lupus. Certain antibiotic medicines may slightly increase the risk of having an Achilles tendon rupture. These are the quinolone antibiotics such as ciprofloxacin and ofloxacin. The risk of having an Achilles tendon rupture with these antibiotics is actually very low, and mainly applies if you are also taking corticosteroid medication or are over the age of about 60.
Often the person feels a whip-like blow that is followed by weakness in the affected leg - usually he or she is not able to walk afterwards. At place where the tendon ruptured, a significant dent is palpable. Often the experienced physician can diagnose a ruptured Achilles tendon by way of clinical examination and special function tests. Imaging techniques, such as ultrasound and magnetic resonance imaging (MRI) allow for a more precise diagnosis.
An Achilles' tendon injury can be diagnosed by applying the Thompson Test (or Calf Squeeze Test) this is where the person who has suffered the injury lies on their front with their legs bent. Whoever is performing the test, usually a doctor, will then squeeze the calf muscle. If the tendon has not ruptured then the foot should point briefly away from the leg.
Non Surgical Treatment
The treatments of Achilles tendonitis include resting the painful Achilles tendon will allow the inflammation to subside and allow for healing. A period of rest after the onset of symptoms is important in controlling Achilles tendonitis. In patients who have more significant symptoms, a period of immobilization can help. Either a removable walking boot or a cast can allow the inflamed tendon to cool down quickly. A heel wedge can be inserted into the shoe to minimize the stress on the Achilles tendon. These can be placed in both athletic and work shoes. Applying ice to the area of inflammation can help stimulate blood flow to the area and relieve the pain associated with inflammation. Apply ice several times a day, including after exercise. The pain and swelling most commonly associated with Achilles tendonitis can be improved with non-steroidal, anti-inflammatory medications (NSAIDs) which include Celebrex?, Advil?, Motrin?, Naprosyn?. Be sure to consult your physician before starting any medications. Physical therapists can help formulate a stretching and rehabilitation program to improve flexibility of the Achilles tendon. Cortisone injections should not be used for Achilles tendonitis. Studies have shown an increased incidence of Achilles tendon rupture after cortisone injections.
A completely ruptured Achilles tendon requires surgery and up to 12 weeks in a cast. Partial tears are sometimes are treated with surgery following by a cast. Because the tendon shortens as it heals, a heel lift is used for 6 months or more after the cast comes off. Physical therapy to regain flexibility and then strength are begun as soon as the cast is off.
